摘要

A method is described of producing soda from the residues obtained in the treatment of crude potassium salts, in accordance with which these residue salts are treated with their aqueous solution at elevated temperature and the liquid phase is separated from the remaining salt which is then treated with an ammonium carbonate- containing dissolving liquor from ammonia-soda production, whereupon the liquid phase which has been separated from the remaining residue is treated with ammonium-magnesium carbonate crystals and stirred, and the desired sodium chloride sol is finally separated from the pulp and introduced into ammonia soda production.
